Manfred Krug (born February 8, 1937 in Duisburg) is a German actor and singer. After moving to East Germany at the age of 13, he worked at a steel plant before beginning his acting career on the stage and, ultimately, in film. By the end of the 1950s he had several film roles, and in 1960 he appeared in Frank Beyer's successful war movie Fünf Patronenhülsen (Five Cartridges). Many more film roles followed, with Krug often cast as a socialist hero. Krug also achieved notability as a popular jazz singer, often in collaboration with composer Guenther Fischer.
